The warm weather will roll over to Friday but is likely to give way to a cooler weekend, Mr Penston said, with temperatures dropping to around 20C or 21C .

British hopes for Wimbledon might have been dashed with the exit of Andy Murray yesterday, but tennis fans looking forward to day 11 of the action at the All England club can be consoled with a dry, warm day.

Finalists at Wimbledon could have to contend with some showers on Saturday and Sunday.

"I wouldn't rule out an isolated shower on Saturday, and there is a risk of a few sharp showers on Sunday," said Mr Penston.
